# 2.2	Limitations of current consumer satisfaction survey systems

I. Issues with offline evaluation systems

* Very costly and time-consuming
* Additional process for data entry
* Impossible real-time data monitoring
* Low accuracy due to sampling issues<br>

II. Issue with online evaluation systems

* Low data credibility due to easy data manipulation
* Lack of integrated platforms due to incompatibility with other institutions
* Too much advertising influence
* Low participation rate due to poor compensation system

Additionally, none of these methods puts extensive focus on user data security. Therefore, the data of the users is susceptible to data theft or permanent loss of valuable data.
